前言“补偿式数字量热计”,是根据“补偿式量热学原理设计而成的。该仪器由恒温槽补偿式量热单元以及微机控制系统三部分构成。本仪器可用于液—固,液—液反应热、溶解热、吸附热、解离热等的测量。与传统的量热仪器相比,本仪器具有如下特点: 1.在热效应测试过程中,体系温度始终被维持基本不变,且等于环境温度。体系与环境之间的温差近于零,因而,不再需要计算热交换改正值。这与传统上根据体系温度变化△v的大小去度量热效应的方法,是完全不同的。2.无论是“吸热”或者是“放热”
Preface The “compensated digital calorimeter” is based on the principle of “compensated calorimetry.” The instrument consists of a constant temperature compensated calorimeter and a microcomputer control system composed of three parts. The instrument can be used for liquid - solid, liquid - liquid reaction heat, heat of dissolution, heat of adsorption, heat of dissociation, etc. Compared with traditional calorimeters, the instrument has the following characteristics: 1. During the thermal effect test, the temperature of the system is always maintained basically unchanged, And is equal to the ambient temperature.The temperature difference between the system and the environment is close to zero, so there is no need to calculate the heat exchange correction value.This is completely different from the traditional method of measuring the thermal effect according to the temperature change of the system ΔV. 2. Whether it is “endothermic” or “exothermic”
